[Richard P. Gabriel <rpg@lucid.com>]

I forgot to add that I didn't like the name ``cell-error'' for that
type. Recall that the two subtypes are named ``unbound-variable'' and
``undefined-function''. Since these equally apply to lexical variables
and functions, cells have little to do with it.

In Pitman's original text, he says that this type of error occurs when
accesing locations, so I think a better name is ``access-error''.

Opinions?
